Can a flexible LED placed on the human heart, brain, or blood vessels diagnose or even treat various diseases? New research suggests these possibilities may soon become a reality.

A team of researchers in South Korea led by Prof. Keon Jae Lee (Department of Materials Science and Engineering, KAIST) has developed a new concept in cancer detection: a biocompatible, flexible gallium nitride (GaN) LED that can detect prostate cancer.

GaN LED, a highly efficient light emitting device, has been commercialized in LED TVs and in the lighting industry. Until now, it has been difficult to use this semiconductor material to fabricate flexible electronic systems due to its brittleness. The research team, however, has succeeded in developing a highly efficient, flexible GaN LED and in detecting cancer using a flexible LED biosensor.

Prof. Lee was involved in the first co-invention of "High Performance Flexible Single Crystal GaN" during his PhD course at the University of Illinois at Urbana-Champaign (UIUC). This flexible GaN LED biosensor utilized a similar protocol to transfer thin GaN LED films onto flexible substrates, followed by a biocompatible packaging process; the system's overall potential for use in implantable biomedical applications was demonstrated.

Prof. John Roger (Department of Materials Science and Engineering, UIUC) said, "Bio-integrated LEDs represent an exciting, new technology with strong potential to address important challenges in human health. This present work represents a very nice contribution to this emerging field."

The paper was published online Sept. 16, 2011 in Elsevier's journal Nano Energy.

Porsche CEO Says Supercar Is Not Dead: Cue the Spyder 918

TheStreet (Apr. 16, 2014) The Porsche Spyder 918 proves that, in an automotive world obsessed with fuel efficiency, the supercar is not dead. Porsche North America CEO Detlev von Platen attributes the brand's consistent sales growth -- 21% in 2013 -- with an investment in new technology and expanded performance dynamics. The hybrid Spyder 918 has 887 horsepower and 944 lb-ft of torque, but it can run 18 miles on just an electric charge. The $845,000 vehicle is not a consumer-targeted vehicle but a brand statement.
